Indonesian pool has something to celebrate. The pairing of Albert Januarta and Irsal Nasution has reached the semifinals of the ISAK Billiard WPA Men's Doubles 10-Ball World Championship. Back home, the run to the last four is being called a historic feat, the first of its kind for the country. The doubles event gathers two-man teams from around the world under the World Pool-Billiard Association banner. Ten-ball is regarded as one of the sharpest tests in professional pool, where a single careless shot can swing a whole match. One more win would put the Indonesians in the final.
